I used to use a guy named Stu who ran 10Ring out of his home. Last time I tried contacting him I didn't receive a response though he was always kind of a hands off low comms guy, I would just email him a dealer he had to send his info to for a transfer then out of the blue a few days later he would respond that the item was ready for pickup.
10-ring.net is still active but his location on google maps says permanently closed so who knows.
